【摘要】 测定鸵鸟精液生理指标 ,结果表明 ,鸵鸟的射精量为 0 1 7～ 2 0 3mL ,精液 pH6 7～7 3,精子密度为 1 5 7～ 48 0亿 /mL ,原精液精子畸形率 3 0 9%～ 1 3 3% ,精子活率范围0 78～ 0 92。对鸵鸟精液用不同稀释液稀释后低温保存效果比较研究 ,初步获得在 0～ 5℃时用改进MEM液作稀释液以 1∶2比例稀释后 ,精子在设计的条件下存活时间平均约 72h ,而相应原精液或 0 85 %NaCl液作 1∶2稀释的精液在同样条件下精子仅能存活约 2 4h更多还原

【Abstract】 Several physiological property of ostrich semen were examined.Semen volume per ejaculation was 0.17～2.03 mL with spermatozoa concentration of one billion five hundred seventy million per milliliter,pH 6.7～7.3,motility 0.78～ 0.92 ,morphological abnormality rate 3.09%～13.3%. The mean survival time of spermatozoa was 72 hours when the semen was diluted 2 times with MEM and stored at 5℃.When the semen was untereated or diluted 2 time with 0.85% NaCl solution and stored at the same temprature, the spermatozoa could only survive for about 24 hours.更多还原
